Application filed September 26, 1917, Serial No. 193,314.. RenewedJulyfi, 1919. .Serial No. 309,480.

To all whom it may concern. a j

Beit known thatI, A DREW B, LOCKI-IART, a citizen of the United States,residing at Redlands, in the county, of SanBernardino and State ofCalifornia, have invented a new and useful Bearing-Shim Vise, of whichthe following is a specification.

The invention relates to a shim holder, and p more particularly to theclass .of vises for it clamping bearing shims used in automo biles. i

The primary object of the invention is the: provision 10f a vise or:holder of this visionof a vise 0r holder of this character,

wherein the formation of raised burs or the displacement of metal fromthe edges of 1 the bearing shim is eliminated, when it is "shim clampedin thevise.

Fig. 2 :isa top plan view showing the being worked upon.

Further objects of the inventlonare the .provisionof a vise or holder ofthis character, which is simple in construction, read- .ily and easilyadjusted both for accommodating the different sizes of shims, and forthe fastening of the device upon a plank, or

in a bench vise, which is capable of firmly clamping a bearing shim, andwhich is strong, durable, and inexpensive to manufacture. 1

With these and other objects view, the

invention consists in. the features of construction, combination, andarrangement of parts, as will be hereinafter fully described,illustrated in the accompanying drawing, and pointed pended. j a H 1 Inthe accompanying drawing 25-: i

1 Similar reference characters indicate correspondlng partsthroughoutthe several views in the drawing:

Referring to the drawing in bios igna'tes generally a clamp, whichinthisin- ,stance is in the form ofa substantially .U-

shaped frame 10, which is provided at one limb terminal with an eye 11,in which is ,adjustably engaged the threaded shank 12,

of a-clamping screw, which at its outer end is formed with a knurledknob 13, while at the opposite inner endis the usual clamp .lJhead lt.Theother limb 15 of the frame 10,, is of substantial dovetail shape incross sections for detachable engagement ina c0rrespondingly shapedcounter-seat or groove 16, formed in the under side or bottom of theblock orbody1l7,,of the bearing shim vise or holderB,hereinafterdescribed.

The block or body 17; of the vi se or holder B, has the counter-seat orgroove 16, extending medially from the front to the rear end thereof, sothat the block or body 17, can be moved off of the limb 15, eitherforwardly or rearwardly of the clamp A. when engaged upon a plank. Thusthe block or body. 17,. of said vise or holder B, can be readily removedp from its clamp A and set within a bench vise of any ordinaryconstruction, or can be fitted on its clamp and thereby be held to aplank or other support. The block or body 17 of the vise Bis pref,erably formed with a rounded front end edge 18, flat straight oppositeside edges 19, and the fiat straight rear end edge 20, as is clearlyshown in Fig. 2 of the drawing, and the straight side edges 19, aredesignedto make easier the clampingofthe vise block or body 17,.within a(bench vise,

. The block or body-l7 has-securedgtherein adjacent to its rear edge 20,spacedpin-like stationary jaws or grips 21, which may be verticallyadjusted and are-formedwith ,inwardly beveled front-knife "edges 22.

The jaws or grips are extended above fthe top face of the block or body17 to; position the knife edges 22 the proper d-istance abovethe planeof thetop: edge of msai l tinker-body 7; f r the engage e of nates'inacireular bore 25, opening through the'rear wall of'the block or body17. The 'slot 24, opens through the topor upper face of the block orbody 17, for a disi tance thereof, and the closed end of said slot 7 isformed with-a forward bevel or incline '26,

for a purpose presentlydescribed. v Suitably fitted within the slot 2 isthe shank 27 of a movable jaw 28, which is formed with a concaveoutwardly beveled inner end- 29', providing a curved kmfe edge 30, thejawq28,-being extended upwardly throughthe slot '24, beyond the top orupper face of the block or body 17,so that its edgeBO will engage {thebearing shim 23 I" in coiiperation with thejaws'21, to clamptlieshimfiupon the top orupper surface of 25- V same the position shownby dotted lines Fig. 2 ofthe drawing. VVhenthe shim said blocker-body 17to securely hold the '23, is'cl'amped by the jaws, it: can be readily tothe desiredthinness to fit inbear ings. p r

The shank {27 of the-movable jaw 28 is formed with a "reduced threadedstem '31,

which extends through the bore 25, opening "through the rear wall ,20,of the block or body""17,"and hasengaged thereon an exter- "jnalknurledelongated nut 32, which works against the blockor body 17, and in thismanner, the movable jaw 28, is manually I adjusted for the clamping orunclamping of a bearing shim in the vise, as is clearly illus- Htratedin Figs. 1,2 and .4 of the drawing.

isfthe disposition .of the stationary jaws or "'gri'ps 21,v andthe'movablejaw 28, relative to each other, that is to say, thestationary jaws or grips 21, are arranged in spaced relation near oneedge of the block or body 17, while the movable jaw 28 approaches orrecedes at an intermediate point between fthe'stationary aws or .grlps21, an'dthese jaws are formed wlth knlfe edges 22 and :30 respectively,to bite the bearing shim when clamped thereby without raising. burs, orotherwise displacing the metal at the edges thereof. The beveled wall 26of the fslot. 24, and the beveledinner end 29, of the jaw'28,xcoa'ct toallow said jaws to-closely {approach the line ofsthe stationaryjaws forthe clamping of extremely small bearing shims. The adjustment of thejaw,28, rela- ,..,tive tothe jaw :21, will-permit many sizes fofbearingshims to be clamped in the vise.

. Another important feature of the vise is e I "that the'sa'me whenmounted uponthe clam A can "be 'fastened "to a plank 1n a workpit in anautomobile repair shop, or said block I or body can be detached from theclamp A,

so that the vise B, can be fastened, in an ordinary bench clamp for usein clamping bearing shims to be filed in the repair shop proper, as willbe clearly apparent.

It is to be understood that changes and modifications may be made in theinvention,

such as come properly within the scope of the appended claims, withoutdeparting from the spirit of the invention, or sacrificing any of itsadvantages.

From the fore oing it is thought'that the construction an. manner ofoperation of the '-111VGI1131011 Wlll be clearly understood,
